I bought a 1979 f250 with a 460 in it. From what I was told the engine was bored .30 over, high compression pistons (10-1 I think), edelbrock intake, kn air intake and the exhaust was done. It's all running on propane and is not a duel fuel set up. The engine runs great but I wanted to check the timing on it just to be sure. Any idea on what the timing should be?

 

Maybe give these guys a call and ask them for assistance?

 

depends on if the distributer has been recurved with different springs and weights. if the distributer is factory, i would add 8-12' checking exhaust emissions for best burn.
check with the above company as they are up on the latest settings.

 

+1 on adding timing
and checking with the "GotPropane" people

 

Propane loves advance, so, on mine it was 10* initial, 38* mech all in by 2200rpm, then 12* vacuum for driveability. I had basically the same setup as yours(don't know what cam you have).
